from formatting units 14 and 18, respectively, and, based upon
the information contained in the headers, processes the
originating raster so that “the data comprising the raster is
in the target format, i.e. it has the characteristics
indicated in the header 22 of FIG. 2, i.e. the data is in the
universal format but it has the characteristics needed for
display on the receiving device 15" (column 4, lines 6 through
14). Each of the headers 20 and 22 includes information
pertaining to raster size and the number of bits per pixel.
Le Gall indicates that algorithms may be used to effect
changes in spatial resolution (i.e., convert from one raster
size to another) (column 2, lines 55 through 60, and column2
4, lines 31 through 41), and that conversions involving a
change in data resolution (i.e., the number of bits per pixel)
may be carried out using conventional algorithms (column 4,
lines 41 through 46). Although Le Gall is silent concerning
the specifics of the algorithm for accomplishing changes in
2The examiner is mistaken when he states that “Le Gall
fails to specifically teach the step of downsampling the map
of the digitized image to produce a downsampled map of the
digitized image” (paper number 10, page 8). With respect to
“downsampling,” the teachings of Hirabayashi are merely
cumulative to teachings present in Le Gall.
